Nearly two-thirds (65%) of the TGCrE. coli isolates (n?=?46) were positive for blaCMY-2; the remaining 35% were positive for blaCTX-M, with the blaCTX-M-14 being the predominant (75%, n?=?16) variant detected. Metagenomic DNA was extracted directly from feces and feed samples, and it was tested for 84 antimicrobial resistance genes by using quantitative polymerase chain reaction (PCR) array; selected genes were also quantified by droplet digital PCR. The genes detected from the fecal samples belonged mainly to five antimicrobial classes macrolide-lincosamide-streptogramin B (MLSB; 100% prevalence), TETs (88.1%), β-lactams (71.4%), aminoglycosides (66.7%), and fluoroquinolones (47.6%). β-Lactam, MLSB, and TET resistance genes were also detected from feed samples. Our study serves as a baseline for further studies and to streamline antimicrobial use in mink production in accordance with current regulations as in food animals.The consumption of wildlife meat is traditionally accepted in the Peruvian Amazon; however, little is known about the pathogens present in this type of food. One of the most frequently consumed species is a rodent, the paca (Cuniculus paca) or "majaz" in the Peruvian language. The objective of this study was to determine the presence of Salmonella enterica and its antimicrobial resistance profile in paca carcasses sold in the Belen Market of Iquitos-Peru. https://www.selleckchem.com/products/od36.html An observational, descriptive, cross-sectional study was carried out. Fresh and smoked paca carcasses (72 samples) were evaluated during the low-rain period (July 2019) in the traditional market of Iquitos, in the Amazonian Region. Meat samples were swabbed, and International Standards Organization (ISO) 6579-1 2017 protocol was followed to Salmonella isolation. Antimicrobial susceptibility analysis was performed by the disk diffusion method. In addition, serotyping was performed by using the Kauffmann-White scheme. A total of 25 strains of S. enterica were isolated in the paca carcasses, mainly in fresh carcasses (48.6%). The serovars isolated were Agona (45.8%), Infantis (41.7%), Wangata (8.3%), and Javiana (4.2%). A considerable number of the isolated strains were multidrug resistant (40%). The highest prevalence of resistance corresponded to trimethoprim-sulfamethoxazole (64%) followed by nitrofurantoin (44%), chloramphenicol (40%), cefotaxime (40%), and nalidixic acid (40%). Ten strains isolated (40%) were identified as producers of extended spectrum beta lactamases, all in S. enterica serovar Infantis. This study describes the presence of Salmonella Infantis with multidrug resistance profiles in wildlife meat carcasses, making the consumption of this type of products a risk factor for the development of foodborne diseases in the Amazon region. Institutional Review Board Approval Resolution of Thesis Project N° 024-DACMVZ-DAFCVB-U.CIENTÍFICA-2019.To study the ameliorative capacity of Syzygium cumini fruit Pulp Extract (SPE) on cryopreserved bovine semen, three ejaculates each of three fertile bulls (total nine samples) were collected. Each sample was mixed with semen dilution medium in 12 ratios, centrifuged, and 50% of the supernatant was discarded. The remaining sample was mixed with semen cryopreservation extender (SCE) in 14 ratios. Three aliquots (0.3?mL) of each extended semen sample were further diluted with (1) 0.7?mL SCE (SCE group), (2) 0.7?mL SCE containing SPE equivalent to 7?ppm total antioxidants (SPE7 group), and (3) 0.7?mL SCE equivalent to 14?ppm antioxidants (SPE14 group). For each aliquot, semen quality was analyzed in situ as well as after cryopreservation. Results show significant improvement in sperm membrane integrity, motility, and fertilizability in SPE7 (63.5%?±?2.04%, 56.22%?±?1.7%, 51.1%, respectively) and SPE14 (68%?±?1.12%, 63.67%?±?1.06%, 57.7%, respectively) than the SCE group (62.33%?±?1.22%, 54.9%?±?1.34%, 48.8%, respectively). Similarly, significant improvement in the mean percent number of progressively motile sperm at the expense of the mean percent twitching, shaking, and whirling spermatozoa, both before and after cryopreservation, were observed in SPE7 (72?±?1.06, 61.2?±?1.2) and SPE14 (78.89?±?1.12, 67?±?1.32) groups to that of the SCE (59.6?±?0.97, 52.3?±?3.5). In addition, the mean percent of progressively motile spermatozoa showing 20?μm/s or above velocity, before and after cryopreservation, were significantly higher in SPE7 (58.9?±?4.7, 43.6?±?1.5) and SPE14 (66.9?±?0.8, 51.3?±?0.8) groups than that of the SCE (42.3?±?3.1, 30?±?2.4). These findings indicate that SPE can significantly improve various quality parameters of the cryopreserved bovine semen.In 2017, the African Union established a new continent-wide public health agency, the Africa Centres for Disease Control and Prevention (Africa CDC). Many outbreaks are never detected in Africa, and among outbreaks that are detected, countries often respond slowly and ineffectively. To address these problems, Africa CDC is working to increase early detection and reporting, improve access to diagnostic tests, promote novel laboratory approaches, help establish national public health institutes, improve information exchange between health agencies, and enhance recording and reporting of acute public health events and vital statistics. The health security of Africa will be strengthened by this new public health agency's ability to build comprehensive, timely disease surveillance that rapidly detects and contains health threats.Nurses work closely with residents on a daily basis but may not understand the details about residency training and experience. We investigated our institution to understand misconceptions nurses may have about residents and provide education. Nurses (n = 26) participated in a lecture about residents and were given identical surveys before and after the lecture. Twenty-two nurses (85%) were medical/surgical, 1 (4%) was obstetrical, and 3 (11%) were critical care. In the pre-education survey, nurses were able to correctly identify the main purpose of residency as educational. Most nurses knew that residents arrived at the hospital between 500 and 700 am and that residents could perform bedside procedures. A marked increase was found between correct pre- and post-survey answers in 4 questions interns are doctors (15% vs. 77%), residents' work hours (23% vs. 65%), correct average salary (39% vs. 92%), and correct paid time off (PTO) days per year (8% vs. 85%). Salaries were overestimated, and work hours and PTO were underestimated.
